Wanda wants to buy 4.35 pounds of chicken salad. The grocery store sells chicken salad for $2.29 a pound. How much does the chic

LenKa [72]

This is very simple.

If you want 4.35 pounds, and it's 2.29 a pound, you simply multiply 4.35 by 2.29.

4.35 * 2.29 = 9.9615 or 10

The chicken salad costs $9.9615 or $10, whichever you need.

Mario has a very disorganized sock drawer. Inside, there are 12 black socks and 16 white socks. Without looking, Mario takes one

BlackZzzverrR [31]

Given

12 black socks

16 white socks

Without looking, Mario takes one sock out of the drawer and then takes out another without replacing the first sock

Which expression shows one way to find the probability that he will take out two white socks?

Procedure

for the first white socks

$\frac{16}{16+12}=\frac{16}{28}=\frac{4}{7}=0.5714$

for the second white socks

$\frac{15}{15+12}=\frac{15}{27}=\frac{5}{9}=0.555$

What is the approximate diameter of a sphere with a volume of 113 cm^3

larisa86 [58]

Answer:

B. 6 cm

Step-by-step explanation:

$\text{Take the volume of a sphere and solve for r.}\\V=\frac{4}{3}\pi r^3\\\text{We already know that the volume is 113, so substitute that value.}\\113=\frac{4}{3}\pi r^3\\\text{Divide both sides by 4/3 pi.}\\\frac{113}{\frac{4}{3}\pi}=r^3\\\text{Divide 113 by 4/3 pi.}\\r^3=26.98\\\text{For a more accessible value, round up.}\\r^3 \approx27\\\text{Take the cube root of both sides.}\\r=3$

Now that the radius is known, all we have to do is multiply it by 2 to get the diameter. Here the answer is simply 3 * 2, or 6.
